square today. morsi's opponents clashing with supporters in cities all over egypt. we're now hearing protesters storming the office of the muslim brotherhood and throwing out books and chairs and other things onto the streets. steve harrigan streaming live from cairo with the latest. hi, steve. >> reporter: gregg, behind me we're seeing the start of violence at this major demonstration in cairo. you see crowds off to my right, the tens of thousands who have gathered here beginning to run. we've seen tear gas fired as well as molotov cocktails. this big crowd here today, the biggest we've seen in some time, is really in reaction to what the new egyptian president did yesterday, muhammad morsi issuing some stunning information, first, that any decree he issues will be legal and that any declaration he issues is final and cannot be appealed by anyone, including the courts. the new egyptian president has basically, on paper, put himself above the law here saying the courts have no say, and obviously, there's a lot of people -- tens of thousands of egyptians -- who are not happy with it.
